Abstract: This disclosure describes techniques for identifying blocked paths and network configuration settings that block paths in networks, such as network paths in a virtual private cloud (VPC). The configuration of virtual networks depends on the correct configuration of many networking resources, such as firewalls, security groups, routing lists, access control lists (ACLs), and the like. In some cases, an analysis that uses formal methods can be performed to determine a network configuration of a virtual network. Using the network configuration information, network paths that are blocked and network configuration settings that may be blocking one or more of the network paths can be determined. The PAS can provide an explanation of what is blocking the network paths. For example, the PAS may identify that a configuration setting of a firewall, router, network gateway, an access control list (ACL), and the like may be blocking a network path.

Abstract: A raster scanning x-ray source can be light and small, and can have high resolution. A raster-assembly can be attached directly to and can encircle an x-ray tube. The raster-assembly can adjoin or can be very close to the x-ray tube, resulting in a small and lightweight scanning x-ray source. X-rays can backscatter back into the x-ray tube instead of into a detector, thus improving resolution of the resulting image.

Abstract: A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

Abstract: A computer system enhances guidance information on a display, allowing a user position and orientation in 3D space to be achieved. In some embodiments, the guidance is visual, for example the blurring of display objects not at the desired position. In some embodiments, the guidance is aural, for example placing a sound moving to the desired position. In some embodiments, the guidance is tactile, for example using haptic pads attached to a head-mounted display to push the user in a specified direction. The system may be used to guide the user spatially for the performing of a task, to help the user avoid sensitive components, or to guide the user to position a sensor, such as a camera, in an optimal direction for taking measurements. The system includes head positioning, hand positioning and gaze positioning techniques.

Abstract: A person who is not wearing a hybrid reality (HR) system communicates with the HR system without using a network communications link using a body pose. An image of an individual is captured using an image capture device and a computing device recognizes a body pose of the individual based on the image. The computing device then selects a response body pose based on the recognized body pose and prompts a user of the HR system to perform the response body pose as a response to the individual. The user is a different person than the individual.

Abstract: A system includes beacon devices with phosphor located on their exteriors. The phosphor is formulated to receive first electromagnetic radiation and emit second electromagnetic radiation in response. The system also includes a head-mounted display (HMD) with a display positioned in a field-of-view (FOV) of a user, an emitter positioned to transmit the first electromagnetic radiation, and an imaging device sensitive to the second wavelength range. A processor of the HMD is programmed to receive an image from the imaging device, determine positions of the beacon devices based on the image, establish a path for the user to follow based on the positions of the beacon devices, and provide a visible cue on the display that indicates the path.

Abstract: A first position of a hybrid reality system (DHR) relative to a first real-world object is determined and data associated with an occluded object is received. A viewport is established anchored to a first location on the first real-world object and a first image showing a first virtual view of the hidden portion of the occluded object as it would be seen from the first position of the DHR through the viewport is presented on the DHR overlaid on a first view of the first real-world object. At a second time, a second position of the DHR is determined and a second image showing a second virtual view of the hidden portion of the occluded object as it would be seen from the second position of the DHR through the viewport is presenting on the DHR overlaid on a second view of the first real-world object.

Abstract: A person who is not using a hybrid reality (HR) system communicates with the HR system without using a network communications link using a body pose. Data is received from a sensor and an individual is detected in the sensor data. A first situation of at least one body part of the individual in 3D space is ascertained at a first time and a body pose is determined based on the first situation of the at least one body part. An action is decided on based on the body pose and the action is performed on an HR system worn by a user.

Abstract: A head-mounted display (HMD) provides directional guidance to a user. The HMD obtains a path from a current real-world position of at least a body part of the user to a different real-world position through real-world space and renders an image representing at least a portion of the path through the real-world space. The rendered image is overlaid on a scene of the real-world space and presented to the user on the HMD. An additional sensory stimulus, directed to the user's sense of sound, touch, smell, or taste is provided to the user, in addition to the image, to encourage the user to move the body part along the path.
